Static electricity is the buildup of electric charges on the surface of objects, primarily caused by _________.

• Friction

• Heat

• Light

What is electric current defined as?

• The flow of protons from high to low concentration

• The flow of electrons from a region of high electron concentration to a region of low electron concentration

• The flow of neutrons in a circuit

• The movement of atoms in a conductor.

During a rainstorm, clouds develop distinct regions of (+) and (-) electrical charges. As the charge buildup intensifies, the air between the cloud and ground becomes increasingly charged, leading to a breakdown of the air's resistance, resulting in a discharge of static electricity in the form of ________.

• Thunder

• Rain

• Lightning bolts
